Invertebre animals have no spine. Evolutionists believe that they evolved over millions of years. So, there is no specific date. However, I am not an evolutionist, and as a Christian, I believe that animals in most cases, were as they were when God made them in the week that He made the heavens and the earth. Hope this helped!
